Speaking to Turkey’s parliament on Tuesday, President Erdogan vowed to see his country crush the Kurdish YPG militarily in Syria. He says all preparations for the long-threatened offensive are completed, and the active operations have started.

Erdogan has railed about Kurdish “terrorists” for years, and has long insisted no Kurds be allowed west of the Euphrates River. Now, Erdogan says they will be totally destroyed east of the Euphrates River as well.

Details are scant, beyond Erdogan promising to destroy them, and saying he will “come down hard on the terror organization with more extensive and effective operations.” The US has yet to comment on the matter.
